Answer: If an electron is in the electric field of a nucleus, the electron can occupy only certain energy levels. When it is sitting on one of these energy levels, it does not radiate, it does not loose energy.
Clouds are made of water droplets and ice crystals. A cloud's individual particles are so small, Also that warm air rising from the earth's surface is able to keep them floating in the air.
Electron clouds are the energy levels where the probability of getting an electron is maximum. These float due to the small size which results into rising them from the earth's surface.
What are the electron cloud?
An electron cloud can be defined as the region which is surrounding an atomic nucleus in the atom in which there is a high probability of an electron being located.
If an electron, negatively charged particle is in the electric field of a nucleus, then the electron can occupy only certain energy levels in the atom. When it is sitting on one of these certain energy levels, then it does not radiate, and hence does not loose energy.

Coral reefs are home to a quarter of all marine species on Earth. What is one
consequence of decreased biodiversity in coral reefs?
A. More niche opportunities for land species
B. Increased number of predatory species
C. Increased stability of all other biomes
D. Less seafood in the human food supply
Answer:
D
Explanation:
A is wrong, it's talking about land. B is an increase in biodiversity. C is wrong because other biomes depend on reefs
The one consequence of decreased biodiversity in coral reefs can be increased number of predatory species. The correct option is B.
What are predatory species?Predatory animals are those that kill and then eat other animals, or "prey on" them. Predatory animals include hawks, lions, alligators, and humans. When one party victimizes another for personal gain, the term predator is also used.
Predation is a natural feeding behavior of animals, plants, and microorganisms in which one species feeds on another for survival. Predation is the process by which one animal kills another and consumes it as food.
Increased predatory species may be one of the consequences of decreased biodiversity in coral reefs.
Fish, marine worms, barnacles, crabs, snails, and sea stars are all predators of coral polyps' soft inner tissues. In extreme cases, large predator populations can devastate entire reefs.
Thus, the correct option is B.

O C. Sensory neurons detect problems in blood that are corrected by
the kidneys.
O D. Nerves are the connective tissue in the kidneys.
Answer:
C
Explanation:
The correct answer is C. When sensory neurons detect a problem in the blood, a signal is sent through afferent neurons to the brain. The brain releases a stimulus, likely a hormone through the pituitary, in order to get the kidneys to correct the problem.
The brain is formed by a variety of nervous tissues and connective tissues. The tissues are highly organized and work together to complete a
variety of tasks.

In a population of wolves, the birth rate is 4, the death rate is 3, immigration is 2, and emigration is 3. Calculate the population growth by filling in the formula below. ( + ) – ( + ) = Since the population growth is , the population is
Population growth is defined as an increase in the number of individuals in a population. Thus, the population growth in the above example is zero.
What is Population growth?Population growth is defined as an increase in the number of people in a population or a dispersed group. Population growth is explained as an increase in the number of individuals in a population.
Population growth is defined as an increase in the number of individuals in a population where most communities with high population growth experience limited resources, for example food, while communities with low rates of population growth do not.
This formula is used to find out the population growth of a population; (Birth rate + emigration) – (death rate + emigration).
Given,
Birth rate = 4, the death rate = 3, immigration = 2, and emigration = 3.
Population growth = Birth rate + immigration - death rate -emigration
= 4 + 2 - 3 - 3
= 6 - 6
= 0.
Thus, the population growth in the above example is zero.
